Viewshed Analysis
This activity was a pretty interesting way to see how lighting coverage can be tested before anything is actually built. I used the Viewshed tool in ArcGIS Pro to model how proposed campground lights would cover an area in eastern New York. The project started with the light locations, property boundary, and elevation data, then compared how the coverage changed when the lights were modeled at different heights.
Figure 1. This figure shows the starting setup for the viewshed analysis, including the campground boundary, light locations, elevation raster, and the Light Locations table. The first setup used a 3-meter light height, directional azimuth values, and a 400-meter light radius.
Figure 2. The first viewshed result shows the light coverage using the original 3-meter height. Only a smaller part of the campground was covered by more than two lights, so this setup did not give as much coverage as needed.
Figure 3. After raising the light height to 10 meters, the final viewshed result showed much better coverage. This was a nice comparison because the improvement was easy to see on the map and made the 10-meter setup look like the stronger option.
